SHUTTLE-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 340,823, dated April 27, 1886.

Application filed October 9, 1885. Serial No. 179,433. (No model.)

To all whom it 'may concern:

Be it known that I, GHAELEs SOHILLING, of Auburn, in the county of Cayuga and State of New York, have invented new and useful Improvements in ShuttleOperating Mechanism for Looms, of which the following is a specification.

This invention relates to the shuttle-operating mechanism of looms, and has for its ob- 10 ject to provide a simple, efficient, and convenient mechanism, whereby the picker-staffs of the loom can be stopped and started at the will of the operator.

My invention consists, to that end, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the aecompan yi n g drawings, consisting of two sheets, Figure l is a longitudinal vertical section of thelower portion ofa loom provided with my improvement. Fig. 2is a horizontal section of the same. Fig. 3 is a longitudinal vertical section of the shipper device in line y 3 Fig. 2. Fig. 4 a sectional plan View showing the picker-shafts thrown out of en gagement. Fig. 5 is a vertical cross-section of one of the hearings in line w a, Fig. 2, on an enlarged scale. Fig. 6 is an elevation of the treadlc.

Like letters of reference refer to like in the several figures.

A represents the end frames of the loom, connected by bars A A and b is the camshaft, arranged lengthwise in the lower por tion of the loom, and journaled in bearings a a in the frames A. The shaft b is rotated by any suitable means, and provided with the usual actuating cams or arms, B, which carry rollers I) at their ends.

0 C represent the rock-shafts, arranged underneath the shaft b, and at right angles thereto.

D 1) represent inwardlyprojeoting arms, secured to the rock-shafts and provided at their freeends with inclined faces or shoes (2, against which the rollers I) of the actuating-cams B parts engage in such manner as to depress the arms D, and thereby turn the shafts O inwardly.

E E represent roclvarms secured to the picker-shafts C O, and F represents the picker'staffs arranged on the outer sides; of the frames A on opposite ends of the machine,

and connected with the rock-armsE by rods 6. The picker-staffs F are pivoted near their lower ends to brackets f, secured to the frames A, and have their lower ends connected by rods f and a spring f, which latter tends to draw the lower ends of the picker-staffs toward each other.

Each of therock-shafts O G is journaled with one end in a fixed bearing, 9, secured to the bar A, and with its opposite end in a movable bearing, h. The fixed bearings g are arranged at the ends of the rock-shafts 0, near which the arms E are secured to said shafts, and the movable bearings h are located near the arms D. The bearings h are made movable toward and from the cams B, so that upon moving the bearings h and shafts (l inwardly the arms D are placed in the position in which they are actuated by the cams B, while upon moving the bearings l1 and shafts G outwardly the arms D are moved out of reach of the cams B. The fixed bearings g are made bellanouthed or tapering, to permit of this movement of the shafts G. The movable bearings h are formed in rings H H, which are seated on semicircular blocks or supports I, formed on plates 1', which latter are secured to the bar A? of the loonrframe.

J represents quadrant shaped blocks or stops formed on the inner sides of the rings H H, and adapted to bear against the straight lower sides of the supports 1'.

k represents ashipper-rod, connected at one end to the ring H at the point at which the shaft 0 is journaled in the same, and at its opposite end to the ring H at a point diamet rically opposite to the point at which the shaft 0 is journaled in the ring H.

Z represents the treadle-shaft, arranged at right angles to the cam-shaft b and journaled in the bars A A. The shaft Z is provided with a shipperarm, L, which is connected with the shipper-rod It by a pin, Z, secured to said rod and passing through a slot, Z", in the arm L.

M represents the treadle,sccured to the outer end of the shaft Z, and provided with two arms, in m, arranged at right angles to each other,.or nearly so, so that upon depressing one of the arms the other arm will assume a horizontal position, ready to be acted upon.

\Vhen the parts are in the position shown in Figs. 1 and 2, the arms B on the shaft I) ride over the shoes (I of the rock shafts and depress the shoes and cause the upper ends of the picker-staffs F F to approach each other, whereby the shuttle is thrown to one side or the other of the loom. \Vhen the rollers b have released the shoes (2, the shafts O C and of the arrow in Fig. 1.

picker-staffs are returned to their former position by the spring).

When itis desired to arrest the mechanismfor instance, for the purpose of correcting an irregularity in weavingthe arm on of the treadle M is depressed, whereby the shaft Z is turned in such a direction as to cause the arm L to move the shipper-rod 7c in the direction By this movement of the rod in the rings H H are turned on their supports so as to move the movable bearings h outwardly, thereby moving the rear ends of the shafts O, which are journaled in said bearings, outwardly, and placing the arms D out of reach of the actuating-cams B, as represented in Figs. 3 and 4, whereby the shaft 1) is prevented from communicating motion to the picker-shafts. By depressing the arm m of the treadle the movable bearings are moved inwardly, and the arms D are again placed in the positions in which they are actuated by the arms or cams B. The quadrant-shaped stops J on the rings H H limit the movements of the rings H H to a quarter-turn on their supports. The weight of the shafts O O and connecting parts and the downward pressure which is applied to these parts tend to hold these shafts in their operative position, with the stops J bearing against the straight lower sides of the supports I, as representcdin Fig.1.

By my improved mechanism both shafts O O are simultaneously thrown in or out of engagement with the actuating-cai'ns by simply operating the treadle, thus placing the picker mechanism completely under the control of the operator in a very simple manner.

I claim as my invention- 1. The combination, with the shaft 1), provided with two actuating cams or arms, B B, of two pickershafts, O 0, made movable, to ward and from said actuating cams or arms, pick er-staffs connected with said picker-shafts, and a shipper whereby said movable pickershafts are connected and simultaneously thrown out of or into engagement with the actuating cams or arms at the will of the op orator, thereby stopping or starting the picker mechanism, substantially as set forth.

' 2. The combination, with the shaft 1), provided with two actuating cams or arms, B B, of two picker-shafts, G O, stationary bearings and movable bearings supporting opposite ends of the picker-shafts, and a shipper connecting said movable bearings, and whereby said shafts are simultaneously thrown in and out of their operative position, substantially as set forth.

3. The combination, with the picker-shafts C C, of the movable rings H H, provided with stops J, segmental supports I, upon which said rings turn, and against which said stops engage, and a shipper connecting said rings, substantially as set forth.

4. The combination, with the shaft 1), pro vidcd with actuating cams or arms B, of the picker-shaftsC C, provided with arms D, mov- CHAS. SCHILLING.
